Trigger shoe info

[M&P40]

Looking for a trigger shoe for a Beretta PX-4 Storm in .40 S&W. Have googled, looked on Brownells, Midway, etc. Called Tyler trigger shoes and they never heard of the gun. Any help would be appreciated!

Trigger shoes were popular in the '50s, but not much lately.

Problems:
They add weight to the trigger which does nothing good for the whole system.
They can snag on the holster, causing you to spring an unexpected leak.
They're an answer looking for a question.

Avoid them.
